@dwain.cExcellent, that is just what I needed.
After working with it for a bit this morning, I've determined I need to assign the groups string in a checksum rather than a row_number. Now I don't need to worry about row_number assigments changing erratically when new group combinations are used. The checksum values won't be affected by permissions changes.
Thanks again.

Happy to hear that my suggestion seems to have gotten you on the right track.
My thought question: Have you ever been told that your query runs too fast?
My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.
